## Review summary

Reviews show a generally positive, well-regarded extension that users rely on over years and appreciate ongoing improvements. However, recurring issues include disruptive automatic scrolling when activating the extension, occasional UI visibility and compatibility problems (especially with local pages), and a less-than-perfect pixel scaling that users must tweak manually. A few users note initial setup friction but still consider it a valuable tool when working toward pixel-perfect results.

### Pros

- Generally positive experience with the extension and ongoing improvements.
- Long-term reliability and high user satisfaction (used for years).
- Perceived usefulness and value of the tool for achieving pixel-perfect results.

### Cons

- Unpredictable scrolling behavior when opening the extension, clicking the eye button, or loading pages with the plugin enabled.
- UI visibility/compatibility issues on some setups (GUI can be invisible or not show up, and issues on local file pages).
- Pixel scaling is off and requires manual adjustment (e.g., about 0.92) to get the correct size.
- Occasional usability friction, such as difficulties uploading a new screenshot or understanding certain features.
